Saturday 23rd February is Open Data Day!
Open Data Day is a gathering of citizens in cities around the world to write applications, liberate data, create visualizations and publish analyses using open public data to show support for and encourage the adoption of open data policies by the world’s local, regional and national governments.
The events are open to anyone: from curious citizens to journalists, tech-geeks to scientists, designers to data wranglers. Swing by on the day to hack, have a hangout and wrangle with us!
